Variable Fidelity AeroPropulsoServoElasticity Analysis Tool, Phase I

Completed Technology Project

Project Introduction

CFDRC proposes to develop, validate, and demonstrate a variable-fidelity multi-physics framework for AeroPropulsoServoElastic (APSE) simulations of supersonic vehicles. The proposed effort will leverage previously developed AeroServoThermoElastic (ASTE) framework that will be advanced with newly developed non-intrusive efficient software integration methodology, and extended with the addition of an aircraft engine propulsion module to create an APSE analysis tool for next generation supersonic vehicles simulations. The developed framework will be verified against benchmark cases for accuracy and efficiency. Demonstration of the full capabilities of the technology will be conducted for a representative supersonic transport configuration in a supersonic flow environment. In Phase II, the capability of the framework will be extended by integrating additional NASA and industry preferred computational tools (both high fidelity and reduced order) to the framework. The usability of the framework will be improved by supporting NASA preferred input/output data formats, adding non-linear material models, support for NASA's open Multidisciplinary Design Analysis and Optimization (openMDAO) scripts and further improving the accuracy of the fluid and structure coupling. Validation and demonstration of the framework will be conducted on selected APSE problems. More »
